ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an electrode for a nonaqueous electrolyte secondary battery with fall of an electrode layer restrained even if the electrode layer is thick, and with unevenness of the thickness of the electrode layer restrained in an electrode surface.

SOLUTION: The electrode for a nonaqueous electrolyte secondary battery has formed an electrode layer with a thickness of 50 μm or more on a collector containing a plurality of through-holes arranged so as a through-hole density at the center to be higher than that at either end of the collector.
